A dielectric barrier discharge plasma reactor was applied to the degradation of tetracycline hydrochloride in the aqueous solution. A series of parameters including input power
air-gap distance
initial concentration and air flow rate were investigated for their effects on the degradation efficiency. The results showed that the degradation efficiency was as high as 92% at the optimum degradation parameters:input power 1.3 W
air-gap distance 2.5 mm
air flow rate 150 ml·min-1
tetracycline hydrochloride initial concentration 100 mg·L-1 and treatment time 30 min. The kinetic studies indicated that the degradation of tetracycline hydrochloride followed the pseudo-second-order kinetics. Based on the intermediate products identified by LC-MS
a possible degradation pathway of tetracycline hydrochloride was proposed.
